As the title says, I have a 1992 HZJ73 and I am in the process of hooking up some auxiliary lights for a rear bumper. I found a 6 pin plug at the rear of the truck that isn’t being used and looks like it might be a factory installed plug for trailer lights. I put a meter on the pins and the only one that rings out is the ground wire. I couldn’t get any voltage readings at any of the other pins ( yes, key was on and the rear lights, reverse lights and a directional were all working at the tail lights. I searched several online FSM manuals without any luck. Has anyone dealt with this plug and can shed some light on its purpose and how it works?
